Application filed June 24, 1901.

T0 aZZ whom it may concern.-

Be it known that I, LEO F. ADT, of Troy, in the county of Rensselaer andState of New York, have invented certain new and'useful Improvements inEyeglasses; and Ido hereby declare the following to be a full, clear,and

exact description of the same, reference being had to the accompanyingdrawings, forming a part of this specification, and to the numeralsmarked thereon.

My present invention relates to improvements in eyeglasses, and has forits object to provide means for facilitating the construction,assemblage, and repair thereof and also providing a range of adjustmentgreater than that ordinarily permitted in devices of this generalnature; and to these and other ends the invention consists in certainimprovements hereinafter described, the novel features being pointed outin the claims at the end of this specification.

In the drawings, Figure 1 is a front elevation of a pair of eyeglassesembodying my improvements; Fig. 2, a plan view of the same with one ofthe lenses and connecting parts shown in section on the line a a of Fig.1; Fig. 3, a rear view; Fig. 4, a sectional view on the line b b of Fig.2; Fig. 5, a perspective view showing the various parts of the mountingseparated.

Similar reference-numerals in the several figures indicate similarparts. H

l 1 indicate the lenses, of any suitable construction and provided atthe inner edges withthe transverse perforations for the application ofthe screws 2 of the holding-clips? The clips 3 in the present embodimentof my invention are constructed, as usual, of sheet metal, having thevertically-extending arms 4 4, for engaging the edges of the lenses, andpreferably two parallel perforated ,ears -5, though one of the latter isall that is necessary. On the inner side of the clips are also formedguide-ears 6, separated somewhat, as shown at the right of Fig. 5, or,if desired, these lugs or ears may be connected by a piece 7, said earsforming, whether connected or not, a recess for the reception of thebridgepiece or bow-spring and for the shanks of the nose-guards. 8indicates a bridge-piece or bow, preferably of spring metal, and in thepresent instance extending at an angle to the Serial No. 65,727. (Nomodel.)

vertical plane of the lenses and adapted to rest upon the bridge of thenose of the wearer, the bow or forward portion of said bridge extendingforwardly of the lenses, while the laterally-extendingperforated ends 9project over the clips 3 on the rear of the lenses, said ends beingguided and held between thelugs 6 of the clips. The nose-guards may beof any suitable construction, each embodying a pad 10, which is adaptedto rest upon the nose of the wearer, and the shank 11, which latter ispreferably of more or. less flexible material, andwhe'n the parts'areassembled this shank also extends between the ears 6 on'the clips andover the ends 9 of the bridge or bow, so that the guard, clip, lens, andone end of the bridge may be connected by a single screw 2, extendinglaterally through the perforated lugs and the lens, as shown.

In addition to constructing the parts so thatone screw or attachingdevice connects all of the parts on one sideof the center of the how itwill be noted that the overlapping ends of the bridge, guard, andfclipare arranged in the same horizontal plane, so that front, thereby givingthe glasses the appearance of being much lighter than usual, and,furthermore, by the connection of the ends of the bridge-piece in rearof the lenses, as shown, and extending the parts near the ends close tothe lenses, as shown, not only may the lenses be brought closer togetherfor persons-whose pupilary distance is short, but a greater range oflateral adjustment is permitted by this metal next the lens than wherethe ends of the bridge orspring are attached directly to the edges ofthe lenses, as usual. The shanksof the nose -guard are of such naturethat they may be readily bent or altered to cause the pads to bear withproper force and in proper position upon the sides of thenose of thewearer.

While but a single attaching-screw is provided for each lens, it will benoted that the parts are so arranged and constructed thatdifferent-shaped guards or bridges may be employed, so that the glassesmay be readily adapted for persons having abnormal facialcharacteristics, and any repairs may be readily made or parts replacedwithout destroying the entire mounting or using other means they are notvisible when viewedfrom the of the lens and having its ends extendedlaterally in rear of and substantially parallel with the lenses and thescrews passing through the ends of the bridge,the clips and the lenses,for securing the parts together,

the portion of the bridge ends extendinglaterally of the lenses beingfree for adjustment.

2. In eyeglasses, the combination with the lenses having theperforations near the inner edges, the clips, the bridge having thelaterally-extending ends in'rear of the lenses and the screws passingthrough the lenses and clips and securing the latter to the bridge, theportion of the bridge extending laterally of the lenses being free foradjustment.

3. In eyeglasses, the combination with the lenses having theperforations near the inner edges, the clips, the bridge having thecentral portion extending forward of the lenses, and the ends extendinglaterally over the rear thereof and engaging the clips to preventmovement independently thereof and the securing-screws passing throughthe lenses and clips andengaging the ends of the bridge to securetheparts, the portion of the bridge extending laterally of the lenses beingfree for adjustment.

4. In eyeglasses, the combination with the lenses having theperforations near their edges, and the clips having the ears, of thebridge having the laterally-extending ends arranged between the ears,and the screws passing through the lenses, and the ends of the bridgeand engaging the clips.

5. In eyeglasses, the combination with the lenses having theperforations near their edges, the clips and the nose-guards, of thebridge having the laterally-extended ends arranged on the same side ofthe lenses as the nose-guards and engaging the latter, and the securingdevices passing laterally through the lenses, clips, nose-guards and theends of the bridge.

6. In eyeglasses, the combination with the lenses having theperforations near their edges and the clips having the ears thereon, ofthe bridge having the laterally-extending ends, arranged between theears on the clips,

the nose-guards having the shanks between the ears on the clips and thesecuring devices each passing through the lenses, clips, shanks and theends of the bridge.

7. In eyeglasses, the combination of a lens, a bridge having its endextending over and in a plane parallel with the face of the lens, aseparate nose-guard having a shank in contact with the bridge end on oneface of the lens, and a single fastening device passing laterallythrough the lens, guard-shank, and bridge end.

8. In eyeglasses, the combination of a lens, a bridge-piece having itscentral portion arranged forward of'the lens and the end extending overthe rear face of the lens and substantially parallel therewith, anose-guard having a shank substantially parallel with the face of thelens and on the same side thereof as the bridge end and a singlefastening device extending through the bridge end,

guard-shank and the lens for securing the parts together.

9. In eyeglasses, the combination with the lenses and the clips at theedge thereof, of a bridge separate from the clips having the centralportion extending forwardly of: the lenses and the laterally-extendingends located in rear of the lenses and means for securing the partstogether, the portion of the bridge extending laterally of the lensesbeing free for adjustment.

10. In eyeglasses, the combination with the lenses, of a bridgeconnecting the lenses having its central portion extending forwardly ofthe rear facesof the lenses and the laterally-extending ends locatedupon and secured to the rear sides of the lenses, the portion of thebridge near the nds lying close to the edges of the lenses, andnose-guards located in rear of the lenses and connected to the latterand to the bridge.

11. In eyeglasses the combination with the lenses, and the nose-guardslocated in rear of the latter, of the bridge-piece having the centralportion extending forwardly of the lenses, and the laterally-extendingends secured to the nose-guards and located in rear of the front facesof the lenses, the portion of the bridge extending laterally of thelenses being free for adjustment. 7

12. In eyeglasses, the combination with the perforated lenses having theclips extending from the edges of the lenses to the perforationstherein, of the bridge having the ends extending over the lenses andengaging the clips to prevent lateral movement thereon, the guardsseparate from the clips but adapted to engage therewith and the separatefastening devices extending through the lenses, clips, guards and bridgeends to secure the parts.
